libstdc++: Fix outdated docs about demangling exception messages
The string returned by std::bad_exception::what() hasn't been a mangled
name since PR libstdc++/14493 was fixed for GCC 4.2.0, so remove the
docs showing how to demangle it.
libstdc++-v3/ChangeLog:
* doc/xml/manual/extensions.xml: Remove std::bad_exception from
example program.
* doc/html/manual/ext_demangling.html: Regenerate.
